I have been toying with a Nintendo VS Dualsystem for the past week and am currently working on a 16-in-1 daughterboard to 16 VS games that have a chip count of less than 6.
Since our VS came with VS Super Mario Bros and VS Ice Climber, it contains a RP2C04-4 PPU that will only work with 3 of the games correctly without modification. To assist in translating the palettes i scripted up a quick and dirty palette converter found at http://nesdev.com/rgbppu/
It is not perfect but should help out a bit for anyone playing with the RGB PPU's.
